1

judge something as too low

to think something is less big, less important, less serious, or less difficult than it really is

الگوی کاربرد: to underestimate [something]
اشتباه رایج:
Learners sometimes say *"underestimate about"* (e.g. *"We underestimated about the cost"*). In English, *underestimate* is followed directly by the object: *"We underestimated the cost."* Learners also confuse *underestimate* with *misunderstand*: *underestimate* is about size, amount, difficulty, or importance; *misunderstand* is about not understanding the meaning.

متضادها

فعل B2 action
2

judge someone as too weak

to think a person or group is less strong, less smart, or less able than they really are

الگوی کاربرد: to underestimate [someone/something]
اشتباه رایج:
Learners sometimes use *underestimate* when they only mean *dislike* or *not respect*, but *underestimate* specifically means to think someone is less strong, less smart, or less able than they are. Also, in friendly talk, *"Don’t underestimate me"* can sound a bit strong or defensive; learners may overuse it where a softer phrase like *"Please trust me"* would be more natural.
هم‌معنی‌ها
undervalue (Focuses more on not recognizing a person’s worth or contribution, especially at work.) | discount (Suggests not taking someone seriously or not giving their skills enough weight.)
متضادها
overestimate (To believe someone is more capable or stronger than they really are.) | overrate (To have too high an opinion of someone’s ability or importance.)

اسم B2 entity

estimate that is too low

a guess or number that is too low and not as big as the real one

الگوی کاربرد: [something] is an underestimate
اشتباه رایج:
Learners often confuse *underestimate* (noun) with *underestimation*. Both exist, but *underestimate* is more common when talking about a number or amount (*"an underestimate of the cost"*), while *underestimation* is more common in abstract or formal talk (*"the underestimation of this risk"*). Also, do not say *"an underestimate about"*; use *"an underestimate of"*.
هم‌معنی‌ها
underrating (More about judging importance too low than about specific numbers.) | underassessment (More formal and technical; often used in official or academic contexts.)
متضادها
overestimate (As a noun, an estimate that is too high.) | overstatement (A description or claim that makes something sound bigger or more important than it is.)
ترکیب‌های رایج
